Abstract
In this work, we propose a metamaterial-based microwave sensor. The main body of the proposed sensor is a microstrip coupled complementary spiral rectangular resonator (CSRR). At resonance, a strong electric field is established along the sides of the CSRR creating a very sensitive area to change in the nearby of the dielectric environment. The enhanced proposed contactless sensor uses liquid samples placed normal to the sensor surface retained within capillary glass tubes. Quick analysis of the liquid dielectric properties is carried out by simply replacing the capillary tube with a new sample.The introduced liquid sample shifts the resonance frequency and alters the peak attenuation of the CSRR resonance. The liquid sample dielectric properties may be estimated by establishing an empirical relationship between the resonance characteristics and the liquid complex relative permittivity. In this work, we could improve our device by simple changing of the CSRR shape of a recently published work, this makes improvement on the characteristics of the sensor and lower its working frequency to 1.8GHz.
